I don't believe any of those Russian companies have permits at all. Importers are U.S. based companies, they are what obtain permits and bring the international shipments in and comply with ITAR. It sounds like they are not revoking existing permits to avoid the plethora of litigation that would ensue, slapping what seems like an expiration on the sanction, and then - mark my words - they will indefinitely extend the "sanctions" for various reasons. As time marches on and these U.S. companies need to renew their permits, they will be unable to and the importation will cease entirely.

This is a backdoor way to achieve a permanent ban on importation of all Russian munitions/arms going forward, with little opposition, no legislation, and no judicial review.
